OP5253 - Opto-Isolated 64 Digital Inputs Module
The OP5253 is one of a range of optional versatile Signal Conditioning Interfaces for the Opal-RT Technologies state of the art HIL (hardware in the loop) systems (The OP5000 series). It is planned to be used where electrical decoupling, ground loop elimination is required or in high voltage environment where complete isolation is a must. |

Description
The OP5253 features 64 optically isolated inputs channels. All of those inputs are sampled simultaneously for additional simulation accuracy. It perfectly suited to interface real life environment signals to TTL world for RT-LAB simulator providing perfect electrical isolation and provide a full short-circuit or discharge protection.
Features
32 optically isolated inputs channels
All inputs are sampled simultaneously for additional simulation accuracy.
I/Os can be grouped in parallel for any size bus simulation
User configurable filters, de-bounce time and conditionings inputs
Choice of sink or source inputs (Factory Options for Common Anode or Common cathode)
All inputs accept sources from 4V to 30V and limit the currant via user interchangeable resistors on sockets
Interfaces
Inputs
The Opto-isolated Inputs accept a wide range of inputs voltage ranging from ±4 to ±30V relative to user’s reference. It has a low threshold current typically 6mA. The inputs are current limited by customer’s interchangeable resistor array mounted on sockets. The Resistor value may be changed by user to enable higher threshold and input voltage.
By default the module come equipped with the resistor value is set to 330 Ohms, recommended for 4 to 5 Volts input.
Each input has a reverse voltage protection.
The Signal Conditioning module inputs can be factory ordered to either common anode or common cathode

Interconnections
The OP5253 is a carrier less module (type C). It fit directly into without carriers into the OP5000 series of Hardware In the Loop simulators. Up to four OP5253 can be positioned into a Wanda3U / 4U and up to six into a HIL BOX.
All user interfaces are accessible via a 96 pins 3 x 32 connector.
